QCD fits to neutrino-iron structure functions at NuTeV
This thesis presents a new determination of {Lambda}{sub QCD} from Next-to-Leading Order QCD fits to the Q{sup 2} dependence of neutrino-iron structure functions. This is the first measurement of {Lambda}{sub QCD} which uses a theoretical model that fully accounts for heavy quark production. Compared with previous neutrino measurements, the result has improved understanding of the largest systematic uncertainties on the muon and hadron energy scales. These improvements lead to one of the most precise determination of {alpha}{sub S} at moderate Q{sup 2}. NuTeV is a neutrino-iron deep inelastic scattering (DIS) experiment that collected data during 1996-97 at Fermilab. The key features of NuTeV include its sign-selected beam which produced separate high purity neutrino and antineutrino beams, and its continuous calibration beam which enabled NuTeV to considerably improve the knowledge of energy scales which have dominated uncertainties in the previous measurements
Operation Of The NuMi Beam Monitoring System
The NuMI (Neutrinos at the Main Injector) facility produces an intense neutrino beam for experiments. The NuMI Beam Monitoring system consists of four arrays of ion chambers that measure the intensity and distribution of the remnant hadron and tertiary muon beams produced in association with the neutrinos. The ion chambers operate in an environment of high particle fluxes and high radiation.Physic

Production of w's and study of deep inelastic reactions by very high energy neutrinos
A spark chamber and scintillation counter experiment using very high energy neutrinos is proposed using a total of 2 x 10{sup 18} protons at 500 GeV in Area 1 at NAL. The purposes are simultaneously (1) to search for {nu} + Z {yields} Z + {mu}{sup -} + W{sup +}; W{sup +} {yields} {mu}{sup +}{nu}, e{sup +}{nu}, and various hadron decay modes, (2) to analyze {nu} + A {yields} {mu}{sup -} + {Gamma} ({Gamma} = hadronic products) for large energy and momentum transfers and (3) to search with an unrestricted trigger and good analyzing power for low cross section or exotic reactions in this new energy region
